If you override a rule that contains customizations, you have to include any previous customizations you've applied elsewhere. In this case, @metamask/eslint-config overrides no-restricted-syntax, but then @metamask/eslint-config-typescript overrides the override.
As a quick fix we should copy over the same selectors used in the base package into the TypeScript package. As a long-term fix, however, we should export these selectors from the base package so that if they get updated in the base package they will automatically be updated in the TypeScript package.
